Lipa has spoken out in support of LGBTQ rights in the past, telling the U.K.'s Gay Times in 2016, "I think artists should really use their power and presence on social media to just put it out there and show support".

The woman also alleged that security placed one fan who was ejected in a headlock.

Dua Lipa, the Albanian singer, is not happy that some of her fans were booted out of the concert venue in Shanghai where she was performing on Wednesday.

The rights in China are behind that of the United Kingdom, meaning that the fans who shared the flag were actively persecuted.

Homosexuality is not illegal in China, as of 1997, but the Chinese social media site Sina Weibo did recently make headlines when they announced that posts relating to homosexuality would be taken down (though this ban was eventually reversed following a backlash).

Another concert-goer, who wished to stay anonymous in fear of repercussions, told MailOnline that she saw one fan, a female, being kicked out by several security guards.
